NOTES:
x
The acceptable calibration window is ±40% of the
displayed (default) value. For example, if the display is
1000
μ
S, the values to which it can be adjusted is 600 to
1400
μ
S.
x
If the conductivity reading of the solution is not within 10%
to 100% of the full scale of the selected measuring range,
calibration error occurs; LCD displays “ERR” and flash
electrode annunciator.
x
If the conductivity reading of the solution is beyond the
selected measuring range, calibration error occurs; LCD
displays “Or” (over range), “ERR” and flashes electrode
annunciator.
x
If calibration error occurs, exit form calibration mode by
pressing
Ÿ
and
ź
keys simultaneously.
Calibration is completed. The display shows the calibration factor (FCt).
This serves as an indication of the effectiveness of the sensor which will
degrade with time and usage. An effective sensor should have a
calibration factor of 0.60 to 1.40
4
Press ENT key
to return to measurement mode.
NOTES:
x
If you use a 2-cell conductivity sensor, make sure that the pin 1 and 2
are shorted and pin 3 and 4 are shorted on the J10 connector. (Refer
section 2.3.3 for more details)
x
When calibrating with manual temperature compensation, the
controller automatically changes from the preset process temperature
to the calibration temperature. After leaving the Calibration mode, the
controller switches back to the process temperature (for setting the
calibration temperature and the process temperature, see section 5.3)
WARNING:
If you change the measuring range of the controller after
calibration is done, the controller will reset back to its factory default calibration.
